AutoCAD Case Studies & Practical Application 4 — Questions and Answers
Question 1: A manufacturing firm needs drawings to meet ASME Y14.5 GD&T standards. Which AutoCAD feature best supports adding geometric tolerancing symbols?
- MTEXT with special characters
- TOLERANCE command (Feature Control Frame dialog) (Correct answer)
- QLEADER with tolerance option
- INSERT block from a symbol library
Correct answer: TOLERANCE command (Feature Control Frame dialog)
The TOLERANCE command opens the Geometric Tolerance dialog to build ASME-compliant feature control frames directly.
Question 2: A site plan drawing file has grown to 45 MB and is very slow to save. Which operation should the drafter perform to reduce file size?
- Run AUDIT
- Run PURGE to remove unused blocks, layers, and styles, then SAVEAS (Correct answer)
- Increase RAM on the workstation
- Split the drawing into multiple files
Correct answer: Run PURGE to remove unused blocks, layers, and styles, then SAVEAS
PURGE removes unused named objects (blocks, layers, linetypes, styles) that inflate file size, and SAVEAS writes a clean copy.
Question 3: An engineer must place a callout bubble that automatically updates when the referenced detail sheet number changes. Which AutoCAD feature supports this?
- A static TEXT object
- A field linked to the sheet number property (Correct answer)
- An attribute block with manual editing
- A MLEADER with text
Correct answer: A field linked to the sheet number property
AutoCAD Fields insert live data references (sheet number, date, file name) that update automatically when the source value changes.
Question 4: A firm switches from imperial to metric standards mid-project. The linetype scale for HIDDEN lines appears too small at metric scale. What should be adjusted?
- LTSCALE system variable (Correct answer)
- LWEIGHT setting
- Plot style table
- DIMSCALE variable
Correct answer: LTSCALE system variable
LTSCALE controls the global linetype dash-and-gap scale; adjusting it corrects linetype appearance when units change.
Question 5: A project manager needs to review which team member last saved a shared DWG file and when. Where is this metadata found without opening the file in AutoCAD?
- Right-click the file in Windows Explorer > Properties > Details tab (Correct answer)
- Open the file and check the STATUS command
- Run AUDIT on the file
- Check the DWG layer list
Correct answer: Right-click the file in Windows Explorer > Properties > Details tab
Windows file Properties > Details tab shows last modified date and, for Office-compatible files, the author embedded by the authoring application.
Question 6: A highway designer needs to offset a polyline road centerline by exactly 3.65 m on each side to define lane edges. Which method is most precise?
- Draw parallel lines by eye
- Use OFFSET command with distance 3.65, applied to each side (Correct answer)
- Use COPY with displacement
- Use FILLET to extend edges
Correct answer: Use OFFSET command with distance 3.65, applied to each side
The OFFSET command creates a parallel copy at an exact specified distance from the source object.
Question 7: A drafter needs to annotate a drawing so that dimension text height always plots at 3mm regardless of which viewport scale is used. What is the correct setup?
- Set fixed text height in DIMSTYLE equal to 3mm in model space
- Use annotative dimensions with the annotation scale matched to each viewport (Correct answer)
- Manually resize dimensions in each viewport
- Set DIMSCALE to 1 in all viewports
Correct answer: Use annotative dimensions with the annotation scale matched to each viewport
Annotative objects automatically adjust their display size to match the viewport scale, ensuring consistent plotted text height.
